Juniper Security, Professional (JNCIP-SEC) Sample Questions (Q79-Q84):

NEW QUESTION # 79
You are configuring advanced policy-based routing. You have created a static route with next hop of an interface in your inet.0 routing table

Referring to the exhibit, what should be changed to solve this issue?

A. You should delete the interface-routes configuration under the routing-options hierarchy.
B. You should move the static route configuration to the main routing instance.
C. You should move the inet. o table before the routing instance table in your rib-groups configuration.
D. You should change the routing instance type to virtual-router.

Answer: C

NEW QUESTION # 80
Exhibit:

The Ipsec VPN does not establish when the peer initiates, but it does establish when the SRX series device initiates. Referring to the exhibit, what will solve this problem?

A. The screen configuration on the untrust zone needs to be modified.
B. IKE needs to be added to the host-inbound traffic directly on the ge-0/0/0 interface.
C. IKE needs to be added for the host-inbound traffic on the VPN zone.
D. Application tracking on the untrust zone needs to be removed.

Answer: B

NEW QUESTION # 81
Exhibit:

You are asked to ensure that Internet users can access the company's internal webserver using its FQDN.
However, the internal DNS server's A record only points to the webserver's private address.
Referring to the exhibit, which two actions are required to complete this task? (Choose two.)

A. Configure destination NAT for both the DNS server and the webserver.
B. Disable the DNS ALG.
C. Configure static NAT for both the DNS server and the webserver.
D. Configure proxy ARP on ge-0/0/3.

Answer: C,D

Explanation:
In the scenario where internal users are trying to access the company's web server via its FQDN but the DNS server resolves to a private IP, two key actions are needed:
* Static NAT (Answer B): Since the internal DNS server resolves the web server to its private IP address (10.10.10.4/24), you need to configure static NAT for both the DNS server and the webserver. This will ensure that requests coming from the internet will be translated to the web server's public IP (203.0.113.4) and the DNS server's public IP (203.0.113.2).
Example Command:
bash
Copy code
set security nat static rule-set public-to-private from zone untrust
set security nat static rule-set public-to-private rule dns-server match destination-address 203.0.113.2/32 set security nat static rule-set public-to-private rule dns-server then static-nat-prefix 10.10.10.2/32 set security nat static rule-set public-to-private rule web-server match destination-address 203.0.113.4/32 set security nat static rule-set public-to-private rule web-server then static-nat-prefix 10.10.10.4/32
* Proxy ARP (Answer D): The SRX needs to respond to ARP requests for the public IP addresses of both the DNS and webserver on the interface facing the internet (ge-0/0/3). This allows the SRX to handle requests directed at the public IPs.
Example Command:
bash
Copy code
set interfaces ge-0/0/3 unit 0 family inet proxy-arp interface-address 203.0.113.2/32 set interfaces ge-0/0/3 unit 0 family inet proxy-arp interface-address 203.0.113.4/32 These two configurations allow external users to access the internal web server via its public IP, as resolved by the DNS server.

NEW QUESTION # 82
You are required to secure a network against malware. You must ensure that in the event that a compromised host is identified within the network.
In this scenario after a threat has been identified, which two components are responsible for enforcing MAC-level infected host?

A. EX Series device
B. Policy Enforcer
C. SRX Series device
D. Juniper ATP Appliance

Answer: A,B

Explanation:
You are required to secure a network against malware. You must ensure that in the event that a compromised host is identified within the network, the host is isolated from the rest of the network.
In this scenario, after a threat has been identified, the two components that are responsible for enforcing MAC-level infected host are:
C) Policy Enforcer. Policy Enforcer is a software solution that integrates with Juniper ATP Cloud and Juniper ATP Appliance to provide automated threat remediation across the network. Policy Enforcer can receive threat intelligence feeds from Juniper ATP Cloud or Juniper ATP Appliance and apply them to the security policies on the SRX Series devices and the EX Series devices. Policy Enforcer can also enforce MAC-level infected host, which is a feature that allows you to quarantine a compromised host by blocking its MAC address on the switch port. Policy Enforcer can communicate with the EX Series devices and instruct them to apply the MAC-level infected host policy to the infected host1.
D) EX Series device. EX Series devices are Ethernet switches that can provide Layer 2 and Layer 3 switching capabilities and security features. EX Series devices can integrate with Policy Enforcer and Juniper ATP Cloud or Juniper ATP Appliance to provide automated threat remediation across the network. EX Series devices can support MAC-level infected host, which is a feature that allows them to quarantine a compromised host by blocking its MAC address on the switch port. EX Series devices can receive instructions from Policy Enforcer and apply the MAC-level infected host policy to the infected host2.
The other options are incorrect because:
A) SRX Series device. SRX Series devices are high-performance firewalls that can provide Layer 3 and Layer 4 security features and integrate with Juniper ATP Cloud or Juniper ATP Appliance to provide advanced threat prevention. SRX Series devices can receive threat intelligence feeds from Juniper ATP Cloud or Juniper ATP Appliance and apply them to the security policies. However, SRX Series devices cannot enforce MAC-level infected host, which is a feature that requires Layer 2 switching capabilities and is supported by EX Series devices3.
B) Juniper ATP Appliance. Juniper ATP Appliance is a hardware solution that provides advanced threat prevention by detecting and blocking malware, ransomware, and other cyberattacks. Juniper ATP Appliance can analyze the network traffic and identify the compromised hosts based on their behavior and communication patterns. Juniper ATP Appliance can also send threat intelligence feeds to Policy Enforcer and SRX Series devices to enable automated threat remediation across the network. However, Juniper ATP Appliance cannot enforce MAC-level infected host, which is a feature that requires Layer 2 switching capabilities and is supported by EX Series devices.

NEW QUESTION # 83
You want to test how the device handles a theoretical session without generating traffic on the Junos security device.
Which command is used in this scenario?

A. show security policies
B. show security flow session
C. show security match-policies
D. request security policies check

Answer: D

Explanation:
The request security policies check command allows you to simulate a session through the SRX device, checking the security policy action that would apply without needing to send real traffic.
This helps in validating configurations before actual deployment.
The command request security policies check is used to test how a Junos security device handles a theoretical session without generating actual traffic. This command is useful for validating how security policies would be applied to a session based on various parameters like source and destination addresses, application type, and more.
This command allows you to simulate a session and verify which security policies would be applied to the session. It's a proactive method to test security policy configurations without the need to generate real traffic.
